Allow target overrides of ctors/dtors support advertisement on VxWorks
2018-11-16 Jerome Lambourg <lambourg@adacore.com>
* config/vxworks.h (TARGET_VXWORKS_HAVE_CTORS_DTORS): New macro.
Default to TARGET_VXWORKS_RTP.
(SUPPORTS_INIT_PRIORITY): Use TARGET_VXWORKS_HAVE_CTORS_DTORS instead
of TARGET_VXWORKS_RTP.
* config/vxworksae.h: Also define TARGET_VXWORKS_HAVE_CTORS_DTORS.
* config/vxworks.c: Use TARGET_VXWORKS_HAVE_CTORS_DTORS instead
of TARGET_VXWORKS_RTP to set targetm.have_ctors_dtors.
